* Note: A securities rating is not a recommendation to buy, sell or hold securities and may be subject to revision or withdrawal at any time.

We expect that delivery of the notes will be made against payment therefor on or about May 9, 2012, which is the fifth business day after the date hereof. Under Rule 15c6-1 of the Exchange Act of 1934, trades in the secondary market generally are required to settle in three business days, unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade the notes on the date hereof or the next following business day will be required, by virtue of the fact that the notes initially will not settle in T+3, to specify an alternative settlement cycle at the time of such trade to prevent a failed settlement and should consult their own adviser.
